25.9 Lewis Dot Structure

Question 1

are d subshells considered valence electrons?

Answer 1

no

Question 2

how to calculate formal charge

Answer 2

FC = # valence electrons - (lines + dots)

Question 3

best Lewis structure characteristics

Answer 3

1) full octets on all atoms
2) minimize formal charge
3) negative formal charge on most EN atom (or + formal charge on least EN atom)

Question 4

what can move around in a resonance structure?

Answer 4

1) non-bonding electrons

2) double/triple bonds
